Definitions
- a lithium ion secondary battery using a material that is alloyed with Li for the negative electrode has a large amount of expansion and contraction at the negative electrode during charge and discharge.
- the volume expansion when occluding Li ions is about 1.2 times in the case of a graphite material, while in the case of Si material, when Si and Li are alloyed, it changes from an amorphous state to a crystalline state and a large volume change
- the Si negative electrode active material there is a trade-off relationship between capacity and cycle durability, and there is a problem that it is difficult to improve high cycle durability while showing high capacity.
- a negative electrode active material for a lithium ion secondary battery which includes an amorphous alloy having the formula; Si x M y Al z .
- M is Mn, Mo, Nb, W, Ta, Fe, Cu, It is a metal consisting of at least one of Ti, V, Cr, Ni, Co, Zr, and Y.
- Patent Document 1 it is described that, in addition to the high capacity, a good cycle life is exhibited by minimizing the content of the metal M in paragraph “0018”.
- a predetermined ternary Si alloy (a ternary Si-Sn-M alloy) is used as a negative electrode active material, and a resin having an elastic modulus of a predetermined range is used as a binder. Is characterized in that it constitutes a negative electrode for an electric device.
- the lithium ion secondary battery to be a target of the present embodiment may be one using the negative electrode for a lithium ion secondary battery of the present embodiment described below, and in particular, regarding the other configuration requirements, It should not be restricted.
- the laminated battery 10 of this embodiment has a structure in which a substantially rectangular power generating element 21 in which the charge and discharge reaction actually proceeds is sealed inside a laminate sheet 29 which is an exterior body.
- Positive electrode active material for example, lithium-transition metal complex oxide, lithium-transition metal phosphate compound, lithium-transition metal sulfate compound, solid solution type, ternary system, NiMn type, NiCo type, spinel Mn type, etc. are mentioned.
- Binder is added for the purpose of binding the active materials or the active material and the current collector to maintain the electrode structure.
- a binder used for a positive electrode active material layer For example, the following materials are mentioned.
- a is preferably 0 ⁇ a ⁇ 0.5, and preferably 0 ⁇ a ⁇ 0.1.
- a method for producing the particle form of the alloy having the composition formula Si x Sn y M z A a there are a solid phase method, a liquid phase method and a gas phase method.
- a plasma melting method or the like can be used.
- a binder, a conductive auxiliary agent, and a viscosity control solvent may be added to the particles to prepare a slurry, and a slurry electrode may be formed using the slurry. Therefore, it is excellent in that it is easy to mass-produce (mass production) and easy to put to practical use as a battery electrode.
- the negative electrode active material layer may contain the other negative electrode active material.
- negative electrode active materials other than the above-mentioned predetermined alloy natural graphite, artificial graphite, carbon black, activated carbon, carbon fiber, coke, soft carbon or carbon such as hard carbon, pure metal such as Si or Sn, or the above predetermined composition Alloy based active material out of the ratio, or TiO, Ti 2 O 3 , TiO 2 , or SiO 2 , metal oxides such as SiO 2 , SiO, SnO 2 , lithium such as Li 4/3 Ti 5/3 O 4 or Li 7 MnN And complex oxides of lithium and transition metals, Li-Pb alloys, Li-Al alloys, Li and the like.
- the content of the predetermined alloy in the total amount of 100% by mass of the negative electrode active material is preferably from the viewpoint of sufficiently exerting the effects exhibited by using the predetermined alloy as the negative electrode active material. It is 50 to 100% by mass, more preferably 80 to 100% by mass, still more preferably 90 to 100% by mass, particularly preferably 95 to 100% by mass, and most preferably 100% by mass.
- the value of the E elastic modulus of the binder depends on the material of the binder, the concentration of the slurry (solid-liquid ratio), the degree of crosslinking, and the heat history such as the drying temperature, the drying rate and the drying time. In this embodiment, by adjusting these, the E elastic modulus of the binder can be adjusted to the above-described desired range.
- the content of the conductive additive mixed into the active material layer is in the range of 1% by mass or more, preferably 3% by mass or more, and more preferably 5% by mass or more based on the total amount of the active material layer.
- the content of the conductive additive mixed into the active material layer is 15% by mass or less, more preferably 10% by mass or less, and still more preferably 7% by mass or less based on the total amount of the active material layer is there.
- the following effects are expressed by defining the compounding ratio (content) of the conductive aid in the active material layer in which the electron conductivity of the active material itself is low and the electrode resistance can be reduced by the amount of the conductive aid within the above range Ru. That is, without inhibiting the electrode reaction, the electron conductivity can be sufficiently ensured, the reduction of the energy density due to the reduction of the electrode density can be suppressed, and the energy density can be improved by the improvement of the electrode density. .
- a conductive binder having both the functions of the conductive aid and the binder may be used instead of the conductive aid and the binder, or one or both of the conductive aid and the binder may be used in combination.
- a commercially available TAB-2 (manufactured by Takasen Co., Ltd.) can be used as the conductive binder.
- the laminated flat lithium ion secondary battery 50 has a rectangular flat shape, and from both side portions thereof, a positive electrode current collector plate 58 for extracting electric power, a negative electrode current collector The electric plate 59 is pulled out.
- the power generation element 57 is wrapped by the battery exterior material 52 of the lithium ion secondary battery 50, and the periphery thereof is heat-fused, and the power generation element 57 draws the positive electrode current collector plate 58 and the negative electrode current collector plate 59 to the outside. It is sealed tightly.
- the power generation element 57 corresponds to the power generation element 21 of the lithium ion secondary battery (stacked battery) 10 shown in FIG.
- the power generation element 57 is formed by stacking a plurality of unit cell layers (single cells) 19 each including the positive electrode (positive electrode active material layer) 13, the electrolyte layer 17, and the negative electrode (negative electrode active material layer) 15.
- the said lithium ion secondary battery is not restrict
- a wound type lithium ion battery one having a cylindrical shape (coin cell) or one having a prismatic shape (square cell), or such one obtained by deforming such a cylindrical shape into a rectangular flat shape
- cylindrical cells there is no particular limitation, such as cylindrical cells.
- a laminate film may be used as the exterior material, or a conventional cylindrical can (metal can) may be used, and the like.
- the power generation element is coated with an aluminum laminate film. Weight reduction can be achieved by the form.
- the negative electrode and the lithium ion secondary battery using the negative electrode active material for a lithium ion secondary battery of the present embodiment are large in such as electric vehicles, hybrid electric vehicles, fuel cell vehicles, and hybrid fuel cell vehicles. It can be suitably used as a capacitive power source. That is, it can be suitably used for a vehicle drive power supply or an auxiliary power supply where high volume energy density and high volume output density are required.
- the DC power supply 1 (Si target) is 185 W
- the DC power supply 2 (Sn target) is 35 W
- the DC power supply 1 (Si target) was 185 W
- the DC power supply 2 (Sn target) was 22 W
- the DC power supply 3 (C target) was 0 W.
- the DC power supply 1 (Si target) is 185 W
- the DC power supply 2 (Sn target) is 0 W
- the DC power supply 3 (C target) is 30 W.
- Example 2 A negative electrode and a battery were produced in the same manner as in Example 1, except that polyimide (E modulus of 2.10 GPa) was used instead of polyamideimide (E modulus of 2.00 GPa) as the binder.
- Example 5 A negative electrode and a battery were produced in the same manner as in Example 1, except that polyimide (E modulus 7.00 GPa) was used as the binder instead of polyamideimide (E modulus 2.00 GPa).
